Accept

The wedding ceremony is a grotesque parody of human tradition, you are **** to wear a veil, and white nylons, but you are nude, the goblins makes you walk using a collar with a leash and your "vows" are nothing more than an angry warning from the chieftain: "Fail him, and I’ll make you wish I’d just flayed you alive."

Then, silence. The door of the son’s hut slams shut, leaving you alone with your new husband.
"Father expects me to break you" he says at last. "And I will not fail him"

Then, the nightmare starts, you try to escape multiple times but after a long and painful training, you are finally broken.
After 7 months, the doors open, and you are squatting at the side of your husband, with milk leaking from your pierced nipples and cum overflowing your plugged pussy. Everyone is talking about your screams, and they imagine what kid unspeakable things the son of the chieftain did to you to transform the courageous human into an obedient and broken wife.

You can't think, you only smile, you want to please him to avoid pain and more humiliation, you want to live for him...
Broken and degraded, you finish your days at his side, and you never return to your world.

Bad ending
